Home Diagnosis hosts Grace and Corbett Lunsford show the process of testing the gigantic old tree growing over their tiny house and normal sized new house. The question: whether to trust it and let it grow, or cut it down before it crushes important stuff. See how it works, and what the verdict was!
Home performance articles and stories from the field with internationally respected building forensics guru Corbett Lunsford at the Building Performance Workshop. Hear new episodes of the Building Performance Podcast, see new videos from the Home Performance YouTube channel, and learn all about how diagnostic testing (more than an 'Energy Audit') can make home improvement and new home construction a proven process!

Corbett compares the Speck, Foobot, and CPS SmartAir IAQ indoor air quality monitors, and discusses why some measurements are more important than others.
Corbett hired Geoff Hebner of Padstone Geotechnical Engineering to ensure the house being built will stand for a hundred years or more.
In part 2, Corbett shows the grading and leveling process with 6-8" lifts and 4x compaction using a remote-controlled trench roller.
In Part 3, Geoff returns to run a simple geotechnical test on the compacted dirt before pouring concrete, and Corbett finds out he's not as slick as he hopes.
FINALLY, we get to pour the concrete once the footings are finished with rebar, and well-supported per Geoff’s geotech engineering specs.

If you only learn one video's worth of HOMEChem, this is the one to watch. Hear principal investigators Delphine Farmer and Marina Vance, joined by Lea Hildebrandt Ruiz and Richard Corsi and the rest of the HOMEChem researchers, describe the complexity they uncovered in this seminal study.

Indoor Air Quality is being explored at breakneck speed with the HOMEChem Experiment, and not surprisingly, ozone (O3) is proving to be the original villain in the complex system of interactions that make the air we breathe much more worrisome than anyone guessed. Featuring HOMEChem scientists Marina Vance, Delphine Farmer, Charlie Weschler, and Richard Corsi.

Charlie Weschler sits down with Grace and Corbett and gives fascinating examples of the complexity of indoor air chemistry. He is an air quality legend, a professor on 3 continents, and one of the nicest guys you'll ever meet. More at: http://HomeDiagnosis.tv/homechem
Corbett and Grace report from HOMEChem in Austin during the open house extravaganza.
Grace and Corbett report from the frontier of indoor air quality, HOMEChem (House Observations of Microbial and Environmental Chemistry). This is their crash course in the instruments that were assembled for this experiment, and the experience of having those millions of dollars of chemistry instruments take a long, hard smell of your offgassing.
Grace and Corbett tour the Center for Energy and Environmental Resources with THE TRAVELER of HOMEChem, Lea Hildebrandt-Ruiz. She shows off her atmospheric chemistry laboratory at the University of Texas at Austin, where she's been testing the harmful effects of pollution on tiny pieces of people!
Corbett freaked out about particles from mosquito repellant and spray sunscreen, especially for his 3-month old little girl. Luckily, he has two of the world's top indoor chemistry experts to advise him and Grace.
Welcome to HOMEChem's last Festivity-Associated Kitchen Emissions Study (FAKESgiving) complete with turkey, stuffing, and cranberry sauce cooked like you'd drive a submarine. As House Observations of Microbial and Environmental Chemistry wraps up, we're digging deeper and deeper into how our cooking, cleaning, and hanging out habits affect the air we breathe in homes.
Body Splash or Body Sprays- these teen-loving products carry more than what is listed on the bottle. What is lingering afterwards and what is the chemistry looking like as the school day ends?
Grace and Corbett brain dump on the last day of HOMEChem, as researchers swab the Test House's surfaces for microbe samples.
Corbett likes tools that are sexy and scary at the same time. This flow hood is both. Measure CFM, Drybulb, Wetbulb, Dewpoint, Velocity, and more with this very affordable tool that will help revolutionize the HVAC industry.
Today I talked with Bryan Orr of the HVAC School Podcast about why home performance is the future of all residential construction and home improvement.
Join building diagnostics guru Corbett Lunsford as he tests the airtightness and insulation of the #TinyLab, the highest performance tiny house on wheels in the world. Using a Retrotec 5000 blower door, DM-32 smart gauge, and ThermApp infrared camera, he proves that the #TinyLab is truly a work of science and art at the same time.
